Personal Agents for Privacy Protection

Temporary Supervisor

Dr Roger Clarke


Enormous scope exists for people's data to be appropriated by service-providers, at considerable cost to people's privacy. A range of techniques exist, whereby people who are concerned about such things can protect themselves. Some involve obscuration of data, whereas others create a new identity and/or a new channel for every session, and yet others merge multiple identities together. Tools of this nature are often referred to as PETs (Privacy-Enhancing Technologies). Since PCs emerged in the period 1977-1984, consumers have used software on their own devices, and stored their data there as well. Now services are being offered 'in the cloud', to replace the applications and software on people's own devices (Gmail, Flickr, Google Docs and Zoho, Salesforce, Dropbox, iTunes, etc.). This creates new scope for service-providers and their 'strategic partners', and law enforcement agencies, to take advantage of people's data. Personal agents need to be devised to address these challenges.


Thesis or Project work in this area could take various forms. For example:

  • relevant principles could be extracted from the existing bodies of theory about software agents
  • existing agent services could be investigated
  • existing services of a privacy-invasive nature (e.g. Facebook, Gmail, Chrome, iTunes, Android, Amazon Silk) could be examined to see what scope exists for agents to be used to protect users' privacy
  • specifications for new or improved agents could be written
  • prototypes could be developed, deployed, tested and experimented with
